oi the notch or recess 8 ot the hoot: member hence when the loch" i inlooking position the connector. end of the chain in said notch does notdraw on the locking member but on the hoolr member only or mainly.

In practice when the tree end oi the side chain is to be connected withthe hook the end linlr (as at it) is pa d down on the locking member anit re in the recess or seat 13 ot said member alttil which the techmgmember, serving; a lever drawn over and pressed home to incitingposition best shown in llig' and 4t. lin this movement the iinlr isnrlied to the notch 5) Where it iinds its seat in the bottom. thereofbeing there held. nntii the inching; member tentionaliy disengaged byiforce raising the opposite direction. the linlr id: in the seat It may)e the ordinary practice, but sa' l tin. can be primarily placed in theseat oi? the notch it the chain be loose enough to permit that and theloch: turned down as betore.

The terms ed the pa can. he changed without departing; from the rist ot'the invention a s claim ,d.

d hat ll claim is:

1. It loch: :tor the side chain at an antisirid device consi ot a hookmember on one end ot the side chain, said hoolr mtniher being ofsii'igrlo ply and harin 'r a seat for a linlr at the other end ot saiddo chaim said hoot; member also having); a lochingdevice tl-shaped incros section pivoted to said hoot: member to ddle the s "no saidlocking}; device ha win 5; means thereon for remo: dy en said hoelrmon'dier. said hool: member liar a beveled eds .acili- Eating; theclosing oi? said inching means on said hooh member.

it loclr tor the side chain ct an anti-skid device consisting of a hookmember on one end oi the side chain, said hoot: member beinn; ct singlepi and having a seat tor a link at the other end of said side chaim saidhoot: member havi a loclrii'igr device llieihaped in crossection pivotedto said hoot; member to straddie the same, s; d locking device havingmeans thereon. tor P1110 *ably enga 'i iq said be h memben said lockingmember baring); a seat tor receiving and carr cinrr said linh into itsseat in the heel; when the loclring; member is meted toward closing;position.

5. it. ioelr tor the side chain o'l an anthshid device consisting of ahook member on one end of thesidechain, said hook member being of singleply and having a seat for a link at the other end of said side chain,said hook member having a locking device consisting of a lever ofU-shape in eross seetioi to straddle the hook member and having atemporary seat for said, link, ,saidlever pivoted to the hook member,the said seat for the link in the heel; member projecting beyond theseat for the link in the locking device whereby the stress of the linkis borne by the hook member and not by the locking device in closedposition of the lock.
